Washingtonians: Any Good Last Minute Campground Suggestions?

My wife and our friends have had a camping trip planned for this weekend, but unfortunately the site we were going to stay at is near the Eastern Washington forest fires and the air is still pretty smokey.

I’m hoping that there are some Washingtonians out there that could give me some good suggestions. The details of what we are looking for are below…

Details: Tent campsite for 4 adults preferably near hiking, swimming or both. Ideally we want to find a real campsite in the woods and avoid any KOA type full amenities, groomed lawn campsites.
